Application filed August 2, 1902.

T 00% whom it may concern.-

Be it known that I, STEPHEN P. RUSH, a citizen of the United States,residing at Tyrone,in the county of Blair and State of Pennsylvania,have invented a new and useful Railway- Ohair, of which the following isa specifica- 'tion.

Thisinvention relates to railway-chairs employed at the joints of rails;and one object thereof is to provide a structure which will not onlysecure the abutting ends of the rails together, but will form a bridgeacross the joint thereof, thus obviating the wearing of said ends andthe shocks imparted by the passage of the wheels thereover.

Another object is to provide a structure made up of a few simpleelements that are associated so they will not readily become deranged,the necessity of bolts and nuts which are liable to become loosenedbeing eliminated. Thus a structure is obtained which is well qualifiedfor the hard service to which it is necessarily exposed.

The preferred form of construction is illustrated in the accompanyingdrawings and is described in the following specification.

In said drawings, Figure 1 is a perspective view of the abutting ends oftwo rails, showing the chair in position thereon. Fig. 2 is a verticaltransverse sectional View through the same. Fig. 3 is a horizontalsectional view taken on the line x a: of Fig. 2. Fig. US a perspectiveview of the clamping-block, and Fig. 5 is a perspective view of thewedge-key.

Similar reference-numerals indicate corresponding parts in all thefigures of the drawin s.

The rails shown in the illustrated embodiment of the invention aredesignated by the reference-numerals 10, the head-flanges being providedin the outer edges of their abutting ends with alined seats or recesses11. A baseplate 12 is arranged transversely beneath the abutting ends ofthe rails and is preferably provided at its corners with notches 13,designed to receive the usual spikes 1at,by means of which the base maybe attached to a tie,if desired. This base is provided at its inner endwith an upstanding abutment15,arranged to fit against the inner sides ofthe rails and Serial No.118,164. (no model.)

preferably terminating at the lower edges of the head-flanges, as shownin Fig. 2, so as to permit the free passage of the flanges of thecar-wheels. This abutment is provided with oppositely-extending Wings16, which fit in the inner channels of the rails. The opposite end ofthe base is provided with an upstanding projection 17 in the form of aninturned hook having a guideway 17 in its inner face.

Slidably mounted upon the base, between the rails and the projection 16,is a clampingblock, (designated as a whole by the reference-numeral 18.)This block comprises a neck 19, having at its upper end an upstandinghead 20, which head is adapted to fit snugly in the recesses 11 of therails, thus bridging the joint between them, as is fully illustrated inFig. 1. The neck, furthermore, is provided with oppositely-extendingwings 21, disposed below the head 20 and engaging in the outer channelsof the rails, said wings abutting against the webs thereof. Dowelpins 22extend through the Webs of the rails and have their opposite endsengaging in sockets formed in the corresponding wings 16 and 21 of theabutment and clamping-block, the openings in the web being preferably inthe form of slots 23, which will permit the necessary expansion andcontraction of the rails.

In order to fasten the clamping-block in its operative position, alocking-key 24. is employed, which is in the form of a wedge and isslidably mounted between the clampingblock and the upstanding projection17, a guideway being formed in the rear end of said clamping-block forthat purpose. The key in turn is held against accidental displacement bya locking-tongue 26, secured at one end to an intermediate portion ofthe key and extending longitudinally toward the contracted end thereof.The free end of this tongue is adapted to be bent about the end of theprojection, as indicated in Figs. 1 and 3. This structure has a numberof advantages over the ordinary railjoint. In the first place, the jointis bridged by the head, which also prevents displacement of theclamping-block. The wings 21 also prevent any upward movement of theclamping-block and greatly strengthen the joint. By means of the key thelocking-block may be securely and tightly wedged in place, and this keyis held against displacement by simple though efficient means. Thevarious parts shown are simply and easily constructed and when assembledcoact to make a strong chair which will withstand rough usage and heavytraffic.

From the foregoing it is thought that the construction,operation, andmany advantages of the herein-described invention will be apparent tothose skilled in the art without further description and it will beunderstood that various changes in the size, shape, proportion, andminor details of construction may be resorted to without departing fromthe spirit or sacrificing any of the ad vantages of the invention. I

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combination with rails having recesses in their abutting ends, ofa holdingblock comprising a neck having an upstanding head fitted in therecesses and bridging the joint between the rails, wings extending inopposite directions from the neck and fitting in the channels of therails, said wings having sockets in their inner faces which extend onlypartially through the wings, and pins seated in the sockets of the wingsand engaging the webs of the rails.

2. The combination with rails having recesses in their abutting ends, ofa base arranged transversely beneath the rails, said base having arail-engaging abutment at one end and an upstanding hook at the otherend,

a holding-block slidably mounted on the base and comprising a neckhaving an upstanding head fitted in the recesses and bridging the jointbetween the rails, wings extending in opposite directions from the headand fitting in the channels of the rails, a key interposed between andengaging the upstanding hook of the base and the holding-block, and abendable locking-tongue carried by the key and engaging the upstandinghook of the base to hold said key against displacement.

3. The combination with rails having recesses in their abutting ends, ofa base arranged transversely beneath the rails, a railengaging abutmentlocated at one end of the base and having oppositely-projecting wingsthat engage in the channels of the rails, an upstanding hook located atthe other end of the base, a holding-block slidably mounted on the baseand comprising a neck having an upstanding head fitted in the recessesof the rails and bridging the joint between the same, wings extending inopposite directions from the head and fitting in the channels of therails, said holding-block having a seat in its rear face, and a keyinterposed between and engaging the upstanding hook of the base and theholding-block, being arranged in the seat of the latter. 7

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
